Hi, I have three new-to-me Ultimaker 3 printers. Our IT folks put them on our local 3dprinteros network. Every day or so, one of the three printers will mysteriously enter developer mode. I go through the front panel menu to uncheck the developer mode box and let the printer restart. I confirm that the printer is not in developer mode after it restarts. All is well, until maybe a few days later when I walk past the printer and see it in developer mode again. Then I do the uncheck-reboot-confirm steps again and wait until next time. The four printers (also UM 3) I have had for a couple of years don't do this. Anyone else see this? Anyone have any clues? Thank you!
